Lisa, I am so, sorry to hear about your brother I know that terrible anguish of waiting on those test we just did that with my brother 3 years ago. I first would like to say there is nothing any of you could have done your brother is the only one who can stop his addiction.
How do you get through this, one day at a time and prayer if you have a HP... that is really the only way. Your brother and family will be in my prayers.
